Hi Chris
I use 4 MOT's under transformer oil in a rectangular storage container with
a lip on the inside on which the cover rests so splashes go back into the
container. Mineral oil is apparently OK but don't use motor oil. I ruined a
capacitor using this. Transformer oil is best but costs more. see

Cheers
